TRAVELING LAWN-SPRINKLER.

SPECIFICATION forming part of Letters Patent No. 693,421, dated February is, 1902. Application filed October 13,1900. Serial No. 32,915. (No model.)

My invention relates to improvements intraveling lawn-sprinklers, and has forits ob ject to provide means actuated by the stream of water to draw the sprinkler over the lawn in a predetermined course and so to construct the sprinkler as to make it more efficient and more easily moved than those of ordinary construction.

To that end my invention consists in the features of construction and combination hereinafter described and claimed.

In the accompanying-drawings, forming part of this specification, Figure 1 is a side elevation of my improvedtravelin g sprinkler. Fig. 2 is a plan view of the same.- Fig. 3 is a detail in side elevation showing the devices for throwing the traveling'mechanism'out of action, and Fig. 4 is a view of the means for guiding-the sprinkler in .itstravel.

In the drawings, A represents the frame of the machine, which is supported .by the carrying-wheels 2. Mounted'in the rear of p the frame is a pipe 3, adapted to be coupled-at its lower end to an ordinary garden-hose 4.

Rotatably mounted upon the top of this pipe is a hollow head 5, from which project outwardly hollow radialjarrns 6, provided with discharge-nozzles 7, set at an angle with the arms. As the water escapes from these nozzles it tends to force these nozzles backward,

thus rotating the head in the manner usual in sprinklers of this kind. I

In order to draw the sprinkler over the ground in a predeterminedcourse, there is rotatably mounted in the forward part of the framea toothed gear 8, which isnormally engaged by a pinion 9, mounted upon the lower end of a vertical shaft'l0, arranged in the framework behind the gear'S. Also mount ed in the framework is a controlling-pawl 11, adapted to engage with the pinion. The upper end of the shaft 10 carries a toothed plate 12, the teeth of which are engaged by'vertifrom the head 5.

,cally-slidable pins 13, projecting downward A number of these pins are provided, and they may be drawn up out of or pushed down into engagement with the plate 12. Byvarying the number of pins in loweredor engaging position the speed of the travel of the machine may be regulated as desired.

Supported'upon the gear 8 is a reel of cable or wire 14,-which passes from the reel out through anopening in the boss 15 at the front of the frame and around a series of posts 16 or other fixed 0r relativelyimmovable objects arranged at different points about which it is desired to have the sprinkler travel. The

end of the wire is made fast to the last post As the sprinkling-head is rotated'by the I force of the water passing through it, the pins 13 engage the teethin the plate 12, rotating the plate and, through themediuin of shaft 10 and gears 9 and 8, windingup the reel of wire. '14, and thus drawing the sprinkler-toward the nearest post with which the Wire is connected. As the sprinkler is drawn up to the nearest post by the pull upon the wire the tapered boss 15 will strike the pulley, lifting the wire from it.

with which the wire is connected. To guide the hose 4 as the sprinkler .is turned from one i post to the next, a hose-pulley 20is arranged v Thesprinkler is so balanced that it I tends to tip upward in front, so that it is easily turned and drawn to the next post in the series ley 20 is mounted upon a support21, which may be hinged'to anarm 22, extending from the post along the ground, as shown in the drawings, or toan independent pin-orplate secured to the ground, so that the support is capable of movement in a vertical plane. As I the sprinkler passes between pulleys 1 8 and 20 from one post to the next in the manner described the hose engages the pulley 20 and lifts it up into the position shown in dotted lines in Fig. 4:, whereby the hose is kept off the ground and the turning of the sprinkler in its travel is facilitated.

To throw the driving mechanism out of operation when the sprinkler reaches the last post to which the wire is directly secured, a plate or frame 23 is slidably arranged upon the top of the sprinkler-frame with its outer or forward end projecting beyond the boss 15 and its rear end inclined downwardly and fitting beneath the similarly-beveled circular plate 24, secured upon the under side of the toothed plate 12. \Vhen the sprinkler reaches the last post, the sliding plate 23 will strike the post and be forced backward, lifting the beveled plate 2% and with it the plate 12 and shaft 10, thus raising the pinion 9 out of engagement with the gear 8, as shown in dotted lines in Fig. 8, so that the water will thereafter flow without affecting the driving mechanism of the sprinkler.

I claim- 1. In alawn-sprinkler of the class described, the combination with a carryingframe provided with suitable supporting-wheels, of a sprinkler-head rotatably mounted upon said frame, and having means for connection with a hose, a reel arranged adjacent-thereto, a toothed disk connected with said reel, and means carried by said head for actuating said disk.

2. In a lawn-sprinkler of the class described, the combination with a carrying-frame provided with suitable supporting-wheels, of a sprinkler-head rotatably mounted upon said frame, and having means for connection with a hose, a reel rotatably mounted in said frame, mechanism interposed between said head and reel, said mechanism being intermittently actuated by said head to actuate said reel.

3. Inatraveling lawn-sprinklerof the class described, the combination with a frame provided with suitable supporting-wheels, of a sprinkler-head rotatably mounted upon said frame, means for connecting said head with a hose, a reel rotatably mounted upon said frame, an operative connection between said head and reel, and means for throwing said head and reel out of connection.

4. In a traveling lawn-sprinkler of the class described, the combination with a frame provided with suitable supporting-wheels, of a sprinkler-head rotatably supported by the frame, means for connecting said head with a source of water-supply, a reel mounted upon the frame, operative connection between said head and reel, and means for varying the relative speed of said head and reel.

5. In a traveling lawn-sprinkler of the class described, the combination, with the frame, provided with suitable supporting-wheels of a sprinkler-head rotatably supported upon said frame and provided with discharge-nozzles, means for connecting said head with a supply of water, a cable connecting said frame with a relatively immovable object, and adjustable means actuated by the head in its rotation to wind up the cable, as and for the purpose set forth.

6. In atraveling lawn-sprinkler of the class described, the combination, with the frame provided with suitable supporting-wheels, of a sprinkler-head rotatably supported by the frame and provided with discharge-nozzles, means for connecting the head with a source of water-supply, a reel mounted upon the frame, a cable mounted upon the reel and connected with a relatively immovable object outside the frame, a toothed disk connected with the reel, and projecting pins carried by the head and adapted in the rotation of the head to engage the disk and actuate the reel.
